JAMES HEDRIOK, OF FAVONIA, VIRGINIA.

I-IOOF-IPARER.

Specification of Letters Patent,

Patented Dec. 10, 1907.

Application filed March 23. 1907. Serial No. 364.100-

To all whom it may concern:

Be it known that I, JAMES HEDRIOK, a citizen of the United States, residing at Favonia, in the county of I/Vythe and State of Virginia, have invented new and useful Improvements in IIoof-Parers, of which the following I is a specification.

This invention relates to hoof parers, the object of the invention being to provide a simple and effective farriers implement for cutting and trimming a horses hoof preparatory to applying the shoe thereto and fastening the same thereon.

By means of the implement hereinafter described, the hoof may be pared or trimmed with the greatest possible accuracy, and the implement is so constructed that it is rendered adjustable to hoofsof different sizes, thus rendering the implement as a whole universal in its use.

\Vith the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed.

In the accompanying drawings, Figure 1 is a sectional elevation of a hoof parer embodying the present invention. Fig. 2 is an edge view of the same. Fig. 3 is a sectional view of a hoof parer embodying a double knife or cutter. Fig. 4 is a detail longitudinal section through the double cutter. Fig. 5 is a cross-section through the double cutter, showing the manner of securing the tangs of the cutting blades in place. Fig. 6 is a detail plan view of the spring-pressed detent.

Fig. 7 is a side elevation of a modified form' of hoof parer embodying my invention. Fig. 8 is an edge view of the same. Fig. 9 is a similar view looking at the opposite edge of the tool.

Referring to the drawings, 1 designates the main bearing or positioning crook which is adapted to rest against the outer side of the hoof during the manipulation of the implement. The base of the crook 1 extends transversely with reference to-the length of the handle, as shown at 2, and then extends inward in the plane of the handle to form a shank 3, to which is fitted a suitable handle 4. The transverse portion 2 of the crook is slotted, as shown at 5, to receive the body of a paring cutter 6 which is pivotally co n.

nected at 7 to the shank 3 of the crook, as clearly shown in-Fig. 1.

Referring to Figs. 1 and 3, the cutter 6 is provided with an inwardly extending tang 8 termlnating in a pro ecting stud 9 which 1s received in any one of a series of holes or sockets 10, in a detent 11 which passes through aslot 12 in the shank 3, and is pivotally mounted at 13 therein. The detent 11 extends in rear of the pivot 13 to provide a heel end extension 14, against which presses the free end of a leaf-spring 15, secured at its opposite end 16 to the shank 3.

By means of the construction just described, the inner sharpened edge of the cutter may be adjusted toward and away from the inner bearing face of the crook 1 to accommodate the implement as a Whole to hoofs of different sizes, and to enable a hoof to be pared with accuracy. The cutter 6 is adjusted by pressing the end of the detent 11 away from the tang 8 and moving the stud 9 so as to enter any desired hole or socket-1,0 in the detent, the detent being held in engagement with the stud 9 by means of the beyond the pivot to form a short shank 17 which is provided at opposite sides with dove-tail grooves or recesses 18 adapted to receive, slidingly, the correspondingly dovetailed shanks or tangs 19 of a pair of cutting blades 20, as shown in Figs. 3, 4 and 5. These cutting blades are arranged to converge toward their outer extremities and are heldin place relatively to the shank 17 by means of a cutter blade lock comprising a head or finger piece 21, a screw shank 22 which fits in a threaded opening 23 in the shank 17, and oppositely projecting shoulders or wings 24 which project in diametrically opposite places and enter corresponding notches or sockets in the inner faces of the tangs 19, as shown in Fig. 4. Either or both of the cutting blades 20 may be released by giving a partial turn tothe head 21 of the lock, thus moving the shoulders 24 out of engagement with the notches in the tangs 19, whereupon the tangs are released and the cutting blades may be slid out of on agement with the dove-tail recesses in the s ank 17. This enables the cutting blades to be sharpened and again replaced and fastened in position.

In the operation of the implement, the handle 4, in connection with the shank 3, constitutes a lever, the fulcrum. of which is represented by the crock 1 which bears against the outer surface of the hoof, thus causing the cutter to operate with. a shearing action on'the hoof for trimming or paring and the like. I

Referring to Figs. 7, 8 and. 9 in which a modified form of my invention is illustrated, the numeral. 1 designates the positioning crook pivoted at 2 upon a bearing plate 3 secured at 4 to the shank 5' of the knife holder. The knife 6" is provided with a shank 7 a secured in. a double yoke 8 riveted at 9 to the shank 5 A curved arm 10 formed integral with the shank 5 is provided with a series of holes 11 and secured to the shank 12 of the positioning crook 1 is a de tent 13 pivoted upon a screw 14, and provided with a winged nut 15 for securing said detent in adjusted position. The detent 13 is provided with a finger 16 adapted to engage any one of the holes 11 in the curved bar 10 to hold the'positioning crook at the required distance from the blade 6*; The shank 5 is suitably secured to a handle a, and the operation of the tool is in all respects identical with that already described.

I claim: i

1. A hoof parer comprising a handle, a crook connected rigidly therewith, a cutter pivotally-related to "the crook, and means for adjusting said cutter to vary the distance between the cutter and the bearing face of the crook.

' 2. A hoof parer comprising a bearing crook having a shank, a handle on said shank, a paring cutter pivotally connected to said shank and provided with a tang, and a spring sustained detent mounted on the shank and engaging the tang and permitting the cutter to be adjusted to vary the distance between the cutter and'the crook.

. 3. A hoof parer embodying a crook having a shank, a handle on said shank, a cutter pivotally connected to the shank and provided with a projecting tang, and a pivotally mounted spring sustained detent connected with the shank and provided with a plurality of sockets to engage the tang of the cutter and render said cutter adjustable as to its angle and distance relatively to the crook.

4. A hoof parer embodying a crook having a shank, a handle mounted on said shank, a hoof parerpivotally connected to the shank and provided with a tang, a detent mounted on the shank and having an adjustable engagement with said tang, said cutter embodying a plurality of cutting blades.

5. A hoof parer embodying a paring crook having a shank, a handle on said shank, and an adjustable cutter embodying a tang pivotally connected to said shank, a detent for engaging and rendering said tang adjustable,

oppositely arranged cutting blades having tangs removably fitted in dove-tail recesses in an extension of said tang, and a locking device connected with said extension and having means to engage the tangs of the cutting blades for fastening the same, in place, substantially as described.

6. A hoof parer comprising a handle, a knife connected to said handle, a positioning crook connected to said handle, means for permitting the adjustment of the knife and crook toward and from each other, and

means for holding said parts in adjusted positions.

In testimony whereof, -I affix my signature in presence of two wltnesses.
